CAPONIZING INSTRUMENT Application filed September This invention relatesto caponizing instruments of the class adapted for use in extract ingtesticles of fowls.

The primary object of the present inven t-ion is to provide aninstrument of the above kind which is extremely simple and durable inconstruction as well as efficient in use.

A further object is to provide an instrument of the kind specified whichmay be readily held steady while performing the 0 operation, and bymeans of which a firm grip may be had on the cord so as to insureremoval of all of the testicle without danger of rupture.

Another object is to provide a caponizing instrument which may beeffectively operated by one hand, so as to leave the other hand free tohold the fowl and which will allow clear vision and ready engagement ofthe jaws with the cord, so that the testicle may be extracted with easeand without requiring a large incision. 7

Other objects will appear as the nature of the invention is betterunderstood, and the same consists in the novel form, combination andarrangement of parts hereinafter more fully described, shown in theaccompanying drawing and claimed.

In the drawing:

Figure 1 is a side elevational view of a caponizing instrumentconstructed 4 in accordance with the present invention;

Figure 2 is a top plan view thereof, and

Figure 8 is an enlarged developed fragmentary perspective view showingthe aws and adjacent parts.

Referring more in detail to the drawing, the present instrument embodiesa handle 1ncluding a rod 5 provided at one end with a depending handgrip 6, preferably in the form of an elongated loop integral with therod 5, and provided at its other end wlth an open substantiallytriangular jaw 7, the plane of which is at right angles to that of thehand grip 6. The jaw 7 is preferably lntegrally joined at its apex tothe rod 5 so as to present a transverse gripping bar portion 8 at itsfree forward or outer end, and as shown clearly in Figure 1, the jaw 7extends forwardly and upwardly from the -rod 5,at anobtuse 10, 1927'.Serial No; 218,706.". 7

angle. By reason of this construction and ar rangement, the testicle mayreadily fall with 111 the open center of the jaw, and clear vision alongthe top of the instrument is allowed-for permittlng the jaw to beproperly directed Wltll'QZlSG in a comparatively small incision.

Pivoted to the forward or outer end of the rod or bar 5 is a verticallyswinging jaw 9 arranged to overlie and move toward and away from the jaw7. The jaw 9-is substantially of the same form'as aw 7 so as to pre- Isent a transverse bar portion 10 and adapted to cooperate with'the barportion 8 of jaw 7 to grip the cord at a point between the inner end ofthe cord and the testicle. Pivotedto the rod5 is a-t-rigger 11 arrangedto swing in a vertical plane adjacent to'but forwardly of the hand grip6, the trigger having a suitable finger piece or ri-ng 12 on'its lowerend and having'its upper end operatively connected to the aw 9 by meansof a link 13 extending along and directly above the upper edge of therod 5. The link 13 is connected to the jaw 9 forwardly of and above itspivot 14, and by pressing forwardly on the lower end of the trigger, thejaw 9 may be swung upwardly away from the jaw 7 as shown by dottedlines. in Figure 1, thus allowing the testicle to fall directly betweenand within the jaws. By then pressing rearwardly on the lower end of thetrigger, the cross bar portions 8 and 10 may be caused to firmly gripthe cord so that the testicle may be readily removed without danger ofrupture. The jaws will, of course, be closed when inserting them in theincision, and by reason of their form and arrangement, the incision neednot be large. The jaw 9 is preferably divided at its apex to provideside legs 15 whose free ends are pivoted to and engage opposite sides ofthe bar 5, and connecting these legs forwardly of the pivot 14 is across bar 16 with which the forward end of the link 13 is pivotallyengaged.

Obviously, the trigger may be operated by a finger of the hand grippingthe hand grip 6, thereby leaving the other hand of the user free to holdthe fowl.

Minor changes may be made without departing from the spirit and scope ofthe invention as claimed.

It is possible to remove both testicles through one incision by means ofthe present instrument, without danger of rupturing the artery or thesmall blood vessels.

What I claim as new is:

A caponizing instrument comprising an elongated member, a hand gripdepending from its rear end, a stationary jaw of substantiallytriangular shaped formation fixedly attached at its apex to the forwardend of the elongated member and disposed upwardly at an obtuse anglewith respect thereto, the central portion of the triangular shaped jawbeing cut out, a coacting similar shaped jaw arranged above thestationary jaw, the apex portion of the upper triangular jaw beingdivided, parallel spaced leg members extending from the free ends of thearms of the triangular shaped upper jaw and being pivotally connected toand engaging the respective sides of the aforesaid member adjacent thestationary jaw, a trigger pivotally connected adjacent its upper end tothe elongated member forwardly of the hand grip, an elongated linkpivotally connected at its rear end to the uper end of the pivotedtrigger, the forward end of the link being pivotally connected to thelast-mentioned jaw between the apex portions-of the arms of saidtriangular shaped aw. J In testimony whereof I affix my signature.
